Yes, you can use KActions in context menus!  It's not *quite* as easy as 
normal menus, but it's not hard either.

1. Your XML file should look *something* like this.  Note that your context 
menu should be OUTSIDE of the MenuBar

   <MenuBar>
     <Menu>
     blah blah blah normal menu
     </Menu>
   </MenuBar>
   <Menu name="popupmenu">
     <Title>Cool KPopupMenu Title</Title>
     <Action name="some_context_action" />
   </Menu>

2. Instantiate your actions like normal:

   new KAction( i18n("My Context Action"), ...., "some_context_action" );

3. Get a handle on your popup menu:

  void Blah::mousePressEvent(QMouseEvent* e)
  {
    if ( e->button() != RightButton )
      return;

    QWidget *widget( factory()->container( "popupmenu", this ) );
    if ( !widget || !widget->inherits( "KPopupMenu" ) )
      return;

    KPopupMenu *menu( static_cast<KPopupMenu*>(widget) );
    menu->popup( ... )
  }

The important part of that last snippet was the 'factory()->container(..)'.  
The name in the 'container' needs to be the name of your context menu as 
defined in the XML file.

Hope that answered your question!
